When a product is manufactured, it always has deviations from the ideal CAD-geometry. Therefore, tolerances are assigned to each part. In this paper a method is presented where a designer can generate different nonideal prototypes independently from the proposed tolerances. This is done by defining gap and flush measurements at selected points. The designer can then evaluate whether the product meets the desired aesthetic quality. This information is given to the product developer or tolerance specialist, who assures that the requirements are met. All visualizations that are generated can be viewed in virtual reality, so that the scenes are more realistic, and the interpretations made by the designer are even more reliable.

Keywords: tolerances, visualization, virtual reality
